[The filling machine comprises, in general,

a vibratory carrier l for the jacket 2 ot' the electricfheateiga container 3 from which inlsulation lis'fed into v the jacket, a tamper 4 orcompressing theinsulation in the jacket, as it is being filled, and means tor auto- -matically ,stopping the machine when the ljacket is illed with insulation.

I Vbmtoy carrier.

" The vibratory carrier 1, which may take vthe form of a Vsquare or rectangular rod, is

' provided with an upper bracket 5 and a lower bracket 6 between which the jacket is supported.

These brackets are adjustable on the carrier soas to accommodate jackets of varying @Thevlower arm Aof thefupper bracket 5 ig. 9) carries a removable bushing 7 recessed to receive the upper end of the jacket 2. Bushings having openings of different sizes will, lf=-cou1:se,-.be required-for jackets of different-diameters. f The lower arm of the upper bracket 5 is .provided with -a funnel 8 communicating with the `upper end of the jacketl 2 through the`bus'hing7 and arranged to receive insufA of insulation fromlthe funnel, Athus lessening the waste of insulation.

The container 3 's fastened Lto ithe"-upper arm of bracket 5 so as to hold its'spout'iin vixed relation to the funnelS.'

-The insulation in powdered for 'granular form maybe introduced into the container i3ftlirougl1 'tliefupper end fthereof, which is fprovidedjfwith ayremovablev cap 11.j

The lo'wer lbracket 6 16,' b7landf'8') has a tapered Yyieldin'g'fseat '12l for *receiying the electric heater terminal '13 lrig'idly' fas- 'ftened--tot-he jacket12. 'Theitapered seat 12 forms 'alheadffora -clylinder'or casing 14, "which is `iarrangetl 'to receive a *plunger 1 5. A' 'coiled compression vspring i16 arrangedfjin the cylinder and seated against the plunger I15 and the 'head 12tends to keepthef-cy'lin- 'der `in eievate'cl position. .Thepiston .15 4extends into an opening in the 'braeketfand -is prevented from turning with' respect -thereto by lneanslofa -key 17 held by the bracket 6 and extending into alongitudinal -slotin the piston. f

The piston 15 may be raised and lowered by means'of a cam 18 pivoted on a depending extension ofthe-:bracket G-andcooperating with a roller 19 on the lower end of the piston. The cam 18 Iwhen moved from-its full line to its dotted fline position, as yby means of a handle 20, allows-the piston-15 to move from its upper to its lowerposition carrying'therewith the yieldingseat 12. To keep the jacket 2 straight and thus prevent bending or buckling thereof, 'it is held 'intermedi-ate its ends Yin fixed relation to the carrier 1. For this purpose a bracket 21 rigidly fastened to the carrier 1 and adjustable thereon carries a pair of jaws 22 fastened thereto by means of springs 23, which tend to hold the .jaws f apart. These 'jaws have opposing grooves or slots 24 arranged to receivethe jacket I2 and to'be clamped thereagainst'by means-of a clamping lscrew 25. l

Thus, when arranging the jacket in fthe carrier l, the yielding seat 12 is lowered and Ythe electric heater terminal fastened to the jacket is seated therein. The upper end of 'the jacket is then arranged beneath the into the recessed bushing 7. The jacket is then clamped xbetween y'the-g clamping jaws 22.!'3-'I`he--llower'- dyielding seat insures the .positive engagement of the upper and lower ends of thejacketavith the Vbushing* 7 vand theseat1`2.

Oawer vibrator.

The .vibratory vcarrier 1 is resiliently supported by a bracket 26 (Fig. 6) secured to L" an y:upright oristandard 27. The Vibratory carrier extends through an opening in the bracket 26 and has -a collar 28 adjustable -thereon restingmpon a compressionspring .'29 surrounding lthecarrier 1 and seated on "the"bracket?26.l

A cover'lplate' 37 'Lprevents v"longitudinal --movement lof-*the'roliers 32, andkeeps dirt 'and iother foreign substances out of the `vibrator housing.

lAs't'he disc 30 rotates, the rollers 32 carried thereby success-ively'engage the -roller 33 of the carrier 11, 'and asa roller 32 en- Hgages the 4roller 33. -t-he carrier is forced downward against the action of spring'29. Asaroller 321'1noves out of engagement with fthefrolier'33, the spring'29 forces lthe carrier '1 u upward funtilf' the yroller 33 en ga ges the periphery of the disc 30.

Thus, `during the rotation 1 ofthe disc 30, 'the carrierl israpidly vibrated through a distance determined :by lthe amount which the rollers' 32 yextend beyond the periphery of the-disc"30.

It has -Ibeen found i that satisfactory results are obtained by vibrating the carrier lonesixteenth (13E) of an inch.

Paglia/neng'. javk t4 din vZZf/,tg machina Before ypl-acingthe 'jacket inthe vibratory carrier to vebe'flilled with'iinsul-ation, the Khelical resistor is arranged inthe cjacket .and one endfof-'the resistor-is connected' with be closed with a Atemporary pluginstead of the terminal. ylV-lien the terminal is` rigidly connected to the jacket, no insulation can escape from the end of the jacketv while itis being filled. The jacket may now be placedin Vthe vibratory carrier with the'terminal or plug fastenedthereto resting in the yielding seat 12 of the lower bracket 6 and the upper end of the jacket'positioned in the bushing 7 of the upper bracket, the resistor' extending throughtlie jacket at the open end thereof and upthrough the bushing 7 and funnel 8.,

The tubular tamper isV at this time locked inL lifted' position by means of thel thumb screw 4 9, so that the lower end of the tubular tamperisheld near the upper Varm of'thecarrier bracket 5. 5 lThe hook 61 of the'tension cord -60 may be connected with the free end of the ,resistoig vand Athe resistor placed underthej desired tension by rotating the reel-64:.l The tubular tamper may now be lowered into the -jacket-until its lower endl rests against the terminal or temporary plug.

A The -filling'macliinemay now be started.

in operation by restoring the belt shifter to its running position with the latch 9 9 of` the belt shifter magnet 68 engaging the finger 100 ofthe belt shifter.

The filling machine being in operation, the

vibratory carrier is rapidly'vlvibrated ver. tically and the tamper is periodically liftedA and allowed todrop to compress the insulation in the jacket as itis being filled.

kThe rapid vibration of the insulation container 8 causes the insulation to -flow freely andv evenly therefrom into the funnel Svfrom which it -has an unobstructed path into the jacket. The rapid vibration of the'jacket as the insulation is being fed `into it causes the insulation to fill evenly the space around and about the resistor.l 5 i The annular space or passageway between the Vtubular tamperand the jacket'allows the insulation to flow freely down therethrough..
